KHACHIMO FSP400-60HLN 400W ATX Power Supply

ATX 400W Power Supply for Modern PCs

The KHACHIMO FSP400-60HLN is a 400W ATX unit built for desktop systems that require reliable power delivery with high efficiency. It suits builders assembling new workstations or upgrading existing towers where a Gold-rated supply is preferred. The 80 PLUS Gold certification ensures lower energy waste and reduced heat output during daily workloads. It is not intended for high-end multi-GPU configurations or servers needing redundant power modules.

Modern Standby Support and Silent Cooling

Modern Standby compatibility allows the system to wake from sleep almost instantly while maintaining very low power draw at idle. The Zero RPM fan mode stops the cooling fan completely during light and medium loads, eliminating audible noise for quiet environments. Resonant LLC topology combined with DC-to-DC conversion delivers stable voltages and minimises coil whine. These features work together without requiring additional software or manual configuration.

Build Quality and Connector Implications

The ATX form factor fits standard chassis mounting points for straightforward installation in typical tower cases. Gold-rated components and the LLC resonant design contribute to consistent performance and long-term durability under continuous operation. Clean power output protects sensitive components such as CPUs and storage drives from voltage fluctuation. The fixed cable set means builders must plan routing carefully in compact enclosures.
